Vapor Compression with Secondary Heat-Transfer Media

Description: From Introduction: "The use of a secondary heat-transfer media in a vapor-compression distillation unit was suggested for investigation as a process for saline water conversion because previous studies on the vapor-compression cycle at low temperatures showed that the fixed charges on the compressor are a substantial part of the final water-product cast. Other fluids were evaluated as above, the results of which are shown in table 1. Data on the other fluids shown in table 1 will be found in the appendix."

The Influence of Acoustical Vibrations on Convective Heat Transfer to Liquids

Description: From Introduction: "The research work described in this report consisted of two phases: analytical and experimental. Because of the complexity of the problem of the interaction between acoustical vibrations and heat transfer, the effort to analyze this problem theoretically began with a search for simplified "mathematical models" of the actual physical processes involved."

Pilot Plant Tests and Design Study of a 2.5 MGD Horizontal-Tube Multiple-Effect Plant

Description: From Summary: "Heat transfer coefficients for 2-, 2.5-, and 3-inch diameter horizontal aluminum-brass tubes are presented and correlated as functions of tube diameter, tube spacing, feed rate, feed salinity, heat flux, boiling point, and vapor velocity. A model of the heat transfer mechanism is proposed to explain and correlate the results."

Some effects of roughness on stagnation-point heat transfer at a Mach number of 2, a stagnation temperature of 3,530 F, and a Reynolds number of 2.5 x 10(exp 6) per foot

Description: Report presenting an investigation to determine some effects of surface roughness on heat transfer at the stagnation point. Testing occurred in the ceramic-heated jet laboratory model at a Mach number of 2, a stagnation temperature of 3,530 degrees Fahrenheit, and a stream Reynolds number of 2.5 x 10(exp 6) per foot. Results regarding the variation of stagnation-point heat-transfer coefficient with surface roughness, heat transfer at the stagnation point of a hemisphere, and heat-transfer coefficient are provided.

Aerodynamic heating of a wing as determined from a free-flight rocket-model test to Mach number 3.64

Description: From Introduction: "The primary purpose of the wing instrumentation was to obtain data for use in design of NACA research missiles; however, it is believed that the wing is representative of typical supersonic designs and that the data will be of general use and interest. Only the wing data are reported herein."

An analysis of laminar free-convection flow and heat transfer about a flat plate parallel to the direction of the generating body force

Description: From Introduction: "The problem of free-convection flow as produced by a body force about a flat plate in the direction of the body force was studied at the NACA Lewis laboratory and is treated in a formal and more general manner herein. The method used is somewhat similar to that used in reference 4 wherein consideration was given to the free-convection flow at high Grashof numbers in a horizontal cylinder which had a variable surface-temperature distribution. In addition, the numerical solutions of references 2 and 3 are herein extended to cover a more complete range of variables."

Analysis of laminar forced-convection heat transfer in entrance region of flat rectangular ducts

Description: From Introduction: "Beyond the position where the boundary layer treatment can no longer be used, curves have been faired to connect the Nusselt number results of the present analysis with those of reference 3, in which a parabolic velocity profile is assumed throughout the entire duct length. So that a comparison could be made with the results of reference 3, the boundary layer analysis was used to study the development of the temperature profile associated with a parabolic velocity profile throughout."

Analysis of fully developed turbulent heat transfer and flow in an annulus with various eccentricities

Description: From Introduction: "Most of the existing analyses for turbulent flow and heat transfer in passages have been confined to circular tubes or parallel plates (refs. 1 to 5). In reference 6, temperature distributions for rectangular and triangular ducts were calculated by using experimental velocity distributions and average heat-transfer coefficients. Some work on the calculation of the velocity and shear-stress distributions in corners is reported in reference 7."

Analysis of fully developed turbulent heat transfer at low Peclet numbers in smooth tubes with application to liquid metals

Description: From Introduction: "Analyses of heat transfer for liquid metals flowing turbulently in smooth tubes (low Pradtl numbers) are given in reference 1 and 2. The predicted heat-transfer coefficients from these analyses are considerably higher than those determined in the experimental heat-transfer investigations for mercury and lead bismuth given in references 2 to 4. If the analytical and experimental results for flow of gases are compared at low Peclet numbers, they are also found to be in disagreement (references 5 and 6)."

Preliminary investigation of the transfer of heat from a flat plate at a Mach number of 1.5

Description: From Summary: "Surface temperatures and heat transfer to the air stream have been measured for turbulent flow over a flat plate at a Mach number of 1.5 and at a Reynolds number, based on the momentum thickness of the boundary layer, of approximately 5000. Preliminary data are presented and the surface heat-transfer coefficients calculated from these data are considered to be accurate to plus or minus 2.6 percent at a temperature potential of 50 degrees Fahrenheit. These data are in good agreement with the results produced by applying modifications obtained from published information to existing subsonic theories."
